File content as of revision 1:920482bc63f4:

You need all these files copy into a server with PHP 5.6 and MySQL support.
gpio.txt is not necessary to copy cuz php script will create automatically when file not found.
In MySQL create DTB with tables:
    - Table 'users' with fields 'u_name', 'u_password' and some 'id'
    - Table 'nucleo_data' with fields 'id', 'time', 'date' and 'temp'

Control.php only rewrite one row in database now but MySQL tables and SQL commands in PHP scripts can be simply change for tamperature log.
Login_page.php not have register and forgot password functions. Working only with users writed in MySQL table 'users'.
 
*I do not know why, but when i open control.php in online compiler and scroll down to CSS style, page will freze so maybe export will be better solution than open it here.
